Pure Sealant cures at room temperature by reacting with moisture in the air to become an elastic sealing material with outstanding adhesiveness. It is particularly suited to clean rooms where a high degree of cleanliness is required, and for airtight sealing of semiconductor production equipment and clean room joints for which control of chemical contaminants is a must.

• Excellent durability, heat resistance and weather resistance.
• Low-molecular-weight dimethyl siloxane is almost not evaporated.
• Outstanding adhesiveness.
• Easy-to-use one-component type. Simply squeeze from the cartridge to apply.
• Testing shows that the amount of organic compounds adsorbed to Si wafers is much lower than with common sealants. (Pure Sealant S-type)
• In wafer absorption tests, our Pure Sealant S-type performed far better than conventional sealants.

• Sealing interior trim joints and sealing around air filters, etc. in clean rooms used in the manufacturing and processing of semiconductors and other types of precision electronic materials.

• Pure Sealant : White, light gray, ivory, dark ivory, translucent
