Q1: What substrates does DOWSIL Q2-7406 adhere well to?
A: DOWSIL Q2-7406 is engineered for reliable adhesion to low-surface-energy substrates such as silicone rubber, fluoropolymers, and polyolefins, as well as common high-energy surfaces including metals, glass, and PET. Performance may vary depending on surface cleanliness and pretreatment.
Q2: Is this adhesive suitable for high-temperature applications?
A: Yes — as a silicone-based pressure-sensitive adhesive, DOWSIL Q2-7406 maintains cohesive integrity and tack retention across a broad service temperature range, typically from -65 °C to over 200 °C, making it appropriate for demanding thermal environments.
Q3: How is DOWSIL Q2-7406 typically applied in manufacturing?
A: It is commonly supplied as a solvent-based or solvent-free coating formulation and applied via roll coating, slot die, or gravure methods onto release liners or directly onto substrates. Curing is generally achieved through ambient drying or mild thermal treatment, depending on the carrier system.
Q4: Can DOWSIL Q2-7406 be formulated with additives or blended with other polymers?
A: Yes — it is compatible with various silicone modifiers, rheology adjusters, and crosslinkers to tailor peel strength, shear resistance, and conformability. Blending with non-silicone polymers is possible but requires compatibility evaluation to avoid phase separation or performance loss.
