This page introduces "transparent materials" of "liquid plastics." (For those who are meeting the Kobayashi Kobazoru Division for the first time↓ The Kobazoru Division specializes in the development of a wide variety of liquid plastics. We excel in proposing custom brands tailored to the specific needs and desired specifications of our customers, which large companies find difficult to address.) "Liquid plastics" are in a liquid state at the temperatures we typically experience in our daily lives and solidify when heat is applied or a chemical reaction occurs. Among them, "transparent materials" boast unparalleled technological capabilities and product lineups. For example… - Method of solidification: Heating ⇔ Non-heating - Hardness: Super soft (e.g., artificial bait) ⇔ Hard (e.g., stone) - Examples of functional enhancements: Flame retardancy, static prevention, antibacterial properties, weather resistance, shatterproof properties, adhesion, tackiness, compliance with food sanitation laws, biomass content 【Contents (partial)】 ■ Transparent epoxy Aquarit general catalog ■ Transparent urethane materials ■ Glass coating *For more details, please refer to the PDF materials or feel free to contact us.

Based on the amendment to Article 18, Paragraph 3 of the Food Sanitation Act and Notification No. 370, the transitional period for the "Positive List System for food utensils and containers made of synthetic resin (excluding rubber)" will end on May 31, 2025, and will be fully implemented starting June 1. This guide provides an overview of the system and the obligations for information transmission, clearly explaining the changes brought about by the difficult-to-understand legal amendments, which are abundant online. It also outlines our company's initiatives in response to the legal changes.

Are you struggling with your recent efforts towards the SDGs? Do you want to contribute to the SDGs in any way? Our adhesives can help with that! For example, If you want to reduce utility costs... we can suggest adhesives that cure at room temperature as well as heat-cured ones! If you feel unwell due to solvent odors... we can propose solvent-free adhesives! To contribute as much as possible, we also offer "adhesives" made from biomass-derived materials and biomass materials tailored to your needs. Please take a look at our materials!

Please consult our company for the development of transparent resin! (We have many achievements) Since we use biomass materials, we can contribute to environmental considerations and the SDGs! It is a solvent-free urethane resin that is also gentle on the human body. 【Features】 - Biomass plastic... Reduces petroleum-derived plastics. - High transparency... Can beautifully protect the underlying material and printed surface, giving a sense of luxury. - Elasticity... Not brittle, making it resistant to breaking. - Functional enhancement... Can add functionality while maintaining transparency. (Examples) Weather resistance, antibacterial properties, antistatic properties (static electricity dissipation) For more details, please refer to the catalog and downloadable content. The actual biomass content is also publicly available! Samples can be provided upon request.

The Biomass Mark is a label that can be attached to products that use 10% or more of biologically derived resources. There are several benefits to obtaining this mark: - It allows companies to promote their commitment to addressing environmental issues. - It clearly indicates that the product is environmentally friendly. - Since the mark can only be used on certified products, it helps differentiate them from other products.

Solvent-free and low odor Compatible with hand mixing, injection molding machines, and mechanical stirring Usable time: 8 minutes or more

Due to its low odor, it improves the working environment. It is easy to work with even for beginners. The mixing ratio is 100:100, making measurement simple.

We often hear concerns such as 'the smell is bothersome when using adhesive' and 'heating cannot be applied when curing the adhesive' in bonding and joining scenarios. Kobayashi's high-strength adhesive, utilizing room temperature curing technology, can be applied to the items to be bonded, allowing for a correction time, and achieves over 90% of its final strength within 24 hours. 【Features】 ◆ Capable of bonding the same materials as well as different materials such as metal and FRP ◆ Demonstrates stable bonding strength of over 20 MPa with typical metals (SPCC, SUS, etc.) and FRP ◆ Contains no volatile components such as organic solvents, resulting in low odor and excellent shelf life ◆ No heating required, making it suitable for bonding large items and on-site applications ◆ Resistant to water, oil, organic solvents, and high temperatures At Kobayashi, we are engaged in product development that leverages the flexibility of liquid resin products. We can also consult on controlling properties and working time before curing, as well as improving characteristic values and imparting functionality after curing. *For more details, please download the PDF or contact us directly.

Kobayashi will respond to your requests for "I want this kind of adhesive"! "Can such performance be achieved?" For example... it should not peel off even at 100°C I want to use it in places that get wet. "Can it adhere to this substrate?" For example... what about aluminum? Nylon? Concrete? Additionally, if you want it to cure at room temperature or be solvent-free... Please consult us about your ideas! We will closely address each of your requests and respond to "I want this kind of adhesive"! For more details about what Kobayashi can do and past case studies of problem-solving, please refer to our catalog! *Our product lineup is also included.

Even if you only look at the material information, you may not know if you can create the product you want... You may not know if it can be done with the equipment you currently have... You have a product you want to make, but are you unsure about what equipment and materials to use? Our company provides two-component curing resins (such as urethane and epoxy) in liquid form before molding. We also accept customization according to our customers' requests. Utilizing our experience in various industries, we can offer suggestions not only about materials but also about equipment. Please feel free to consult us about what you want to create! *For more details, please refer to the PDF or feel free to contact us.

For customers who are not satisfied with existing products, we design materials tailored to your needs. Appearance: Transparency, hardness Processing conditions: Viscosity, mixing ratio, usable time Other requirements: Yellowing resistance, shrinkage rate, etc. Please feel free to consult with us.

It does not compromise the design due to its transparent adhesive properties. Additionally, it exhibits excellent flexibility, allowing it to maintain its adaptability even after bending or other processing post-adhesion.

This document introduces Kobayashi's initiatives that believe in the future and potential of plastics. As a mission of a company involved in plastic products, we have focused on recycling and the use of biomass materials early on and have actively pursued development. In order for plastics to coexist with people and the Earth and continue to grow, we will continue to pursue diverse added value in the future.

To interior material manufacturers, we propose an intermediate material that uniformly disperses hard-to-mix components and will introduce examples of how we have resolved issues related to defects and decreased production efficiency. In the company, undispersed materials in the mixture were causing defects such as appearance issues and reduced physical properties. We proposed a paste-like intermediate material that uniformly disperses hard-to-mix components through careful selection of equipment and formulation. This improved defects caused by undispersion and resolved the issue of decreased production efficiency. 【Case Overview】 ■ Background - Defects and decreased production efficiency due to undispersed materials ■ Effects - Resolution of defects caused by undispersed materials - Resolution of decreased production efficiency issues - Prevents material scattering due to its paste-like consistency *For more details, please download the PDF or feel free to contact us.
