"Refle Retreat" is a polymer dispersion using acrylic resin. The polymer particles are small, less than 0.2μ, allowing them to penetrate the underlying concrete, providing excellent water absorption prevention and adhesion enhancement. It maintains stable adhesion strength even at low temperatures (5°C), enabling the application of a follow-up coating method. 【Features】 ■ Stabilizes the adhesion strength of mortar ■ Enables follow-up coating method ■ Excellent water absorption prevention effect ■ Stable adhesion strength even at low temperatures (5°C) ■ Suitable as a primer for repair materials *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our high molecular polymer emulsion sealer, "Lion Bond A." In the application method, it demonstrates excellent water-stopping effects as a primer for ALC and similar materials, making the application of finishing materials easy. In the mixing method, it has a significant water-reducing effect, reduces drying shrinkage, and minimizes skinning, making troweling easier. 【Features】 <Application Method> ■ Stabilizes the adhesion of mortar due to its water absorption prevention effect on concrete substrates. ■ Allows for a follow-up application method. ■ Exhibits excellent water-stopping effects as a primer for ALC and similar materials, facilitating the application of finishing materials. ■ Demonstrates excellent bubble suppression effects as a primer for SL materials, improving surface precision. *For more details, please refer to the PDF document or feel free to contact us.

"Sumisees C" is a suitable membrane curing agent for improving the finish and durability of concrete surfaces. It demonstrates excellent effects for initial curing simply by being applied immediately after concrete placement. As it is a membrane curing agent primarily made of ethylene-vinyl acetate, it can be used as a curing agent for various types of concrete surface finishes. It is particularly effective for jet cement, which tends to dry easily due to the absence of bleeding and high heat generation during curing. [Features] ■ Enables smooth trowel finishing ■ Prevents the occurrence of hairline cracks due to rapid drying ■ Reduces permeability and suppresses carbonation ■ Expected to improve wear resistance *For more details, please refer to the PDF document or feel free to contact us.

"Refletaf Bond" is an epoxy resin adhesive for wet concrete surfaces that excels in adhesion to concrete and steel materials. It demonstrates excellent adhesion even on wet concrete surfaces and can be easily applied with brushes, rollers, etc., making it user-friendly. It can be used for jointing new and old concrete, raising levels, and for applying mortar to old concrete. 【Features】 ■ Excellent adhesion to concrete and steel materials ■ Demonstrates excellent adhesion even on wet concrete surfaces ■ Can be easily applied with brushes, rollers, etc., and is highly user-friendly *For more details, please refer to the PDF document or feel free to contact us.

"Reflegrout" is a non-shrink mortar for large cross-section repairs. It is suitable for injection into large cross-section repair work where thermal stress cracking due to cement hydration heat and drying shrinkage cracking are concerns, as well as for cross-sectional filling methods such as formwork injection methods. Compared to commonly used non-shrink mortars, it has lower hydration heat, which can reduce the thermal stress of the placed components. 【Features】 - It has good fluidity, allowing for pump delivery, etc. - Due to its low hydration heat, it can reduce the thermal stress of the placed components. - Its small drying shrinkage makes it excellent for use in large cross-sections. - It complies with the quality standards of the former Japan Highway Public Corporation's "Cross-Section Repair Material for Formwork Concrete Works." *For more details, please refer to the PDF document or feel free to contact us.

"Refregraut-P" is a non-shrink polymer cement grout that is a pre-mixed type of "Refregraut" with high-performance special powdered resin. It retains the basic properties of "Refregraut," such as high fluidity, low heat generation, and low shrinkage, while also improving the characteristics of polymer cement grout, including resistance to chloride penetration and adhesion. It complies with the standards for structural construction management guidelines for the East, Central, and West Japan Expressway Company. 【Features】 ■ Achieves stable non-shrink polymer cement quality simply by mixing with water ■ Demonstrates significantly higher salt resistance compared to commonly used concrete structures ■ Excellent for use in large cross-sections due to minimal shrinkage from drying ■ Has good fluidity and is pumpable *For more details, please refer to the PDF materials or feel free to contact us.
