Silicone Surfactant
L-6701 is a non-hydrolyzable silicone copolymer specially desinged for use in rigid polyurethane spray foam blown with liquid HCFCs, such as HCFC-141b. Since HCFCs have significantly different solvent potency and vapor thermal conductivity than CFC-11, it is necessary to use a special silicone to obtain optimal k-factor and physical properties. This silicone also gives good results in water-reduced CFC-11 spray foams. L-6701 is unique in the ability to provide good k-factor, excellent surface, fine cell structure and excellent adhesion on rigid polyurethane spray foams.
L-6701 offers superior performance to existing silicones in rigid polyurethane spray foams. A preferred use level of this material is 1.0 part by weight per 100 parts of polyol. However, since optimal concentration is dependent on the requirements of the individual application and formulation, the use level may vary. |
