GF400 is a two part, liquid silicone based gap filler, which provides excellent thermal performance (4.0 W/m.K) and can be cured at room temperature or accelerated with heat. After curing GF400 forms a low modulus elastomer preventing the 'pump-out phenomenon'.
Soft and compliant for low stress applications
Low viscosity; easy to dispense
High thermal conductivity
Low modulus elastomer, prevents 'pump-out'
RoHS Compliant
