OP-3500 offers excellent thermal performance and superior conformability. It is a two-component liquid gap filling material, cured at either room or elevated temperature to speed up the curing process. The pre-curing material possesses good thixotropic characteristics as well as low viscosity which is an ideal solution for dispensing.

After cured, the mixture became a low modulus elastomer to relieve stresses during thermal cycling. OP-3500 will lightly adhere to surfaces, thus improving surface area
contact. The proprietary formulation of OP-3500 is RoHS compliant and halogen-free, providing extra reassurance in applications where hazardous
substances are forbidden.
