Active as seals for wall panels, various equipment, and duct joints in clean rooms! Siloxane-free fluororubber sealant!

= Free samples available! = The high-viscosity fluorine paint "HVF-1" is a high solid content, high viscosity fluorine paint made primarily from fluorine rubber, which excels in heat resistance, chemical resistance, oil resistance, and electrical insulation. It is a siloxane-free sealant that minimizes contact failures in precision equipment. If you are troubled by discoloration due to heat or chemicals, or difficulty in painting due to dripping, please give it a try! Its high viscosity allows for thick application. It can also be used as a sealing agent, filler, or repair material. *Note that shrinkage may occur due to the evaporation of the solvent used. 【Features】 - Made primarily from highly resistant fluorine rubber - Minimizes dripping during application - Excellent chemical resistance, acid resistance (hydrochloric acid, nitric acid, sulfuric acid, etc.), alkali resistance (caustic soda, ammonia, etc.), oil resistance, and heat resistance - Electrical insulation (10^12 to 10^13 Ω·cm) - No silicone used - Low molecular siloxane (D3 to D20) not detected ◎ For more details, please contact us or download the PDF materials. *If you would like a sample, please indicate that.

basic information

**Features of High Viscosity Fluorine Paint HVF-1** - Main ingredient is fluororubber with excellent resistance - Difficult to drip during application - White (gray color is also available separately) - Resistant to discoloration from heat and chemicals - Improved adhesion to substrates through baking (metal-specific primer is also available) - Electrical insulation (10^12 to 10^13 Ω·cm) - No silicone compounds used in raw materials - No detection of low molecular siloxanes (D3 to D20) - Compliant with RoHS/ELV directives (target substances below quantification limits) **Applications** - Sealing of joint surfaces such as piping flanges - Sealing of duct joints - Sealing and repair for chemical etching equipment and semiconductor cleaning equipment - Sealing in painting, optics, precision instruments, and other situations where siloxanes are not allowed - Alternative sealing material for seals and repairs in equipment and devices requiring heat and chemical resistance where silicone materials cannot be used **Siloxane Damage** The outgassing that occurs over time or due to heat from silicone sealants is referred to as siloxane gas. The siloxane gas that is generated can adhere to semiconductor wafers, causing adhesion issues, or form oxides at semiconductor contact points, leading to contact failures. For more details, please refer to the electronic book.
