SikaSeal 330 Heat Curing Seam Sealant Overview

SikaSeal 330, the heat-curing, high-temperature seam sealer specifically designed for powder coat applications. SikaSeal-330 is a one-component, cold-applied, heat-curing acrylic plastisol sealant that delivers a Class A finish and is compatible with various powder coat chemistries. It is suitable for use on aluminum, steel, and galvanneal, making it ideal for truck bodies, cabs, and other manufacturing units. SikaSeal 330 cures during the paint or powder coat process, with a heating temperature range of 375°F to 446°F (190°C to 230°C), making it perfect for e-coated metals and treated substrates. This seam sealer ensures no sealer read-through and maintains flexibility after curing, providing an enhanced finish quality.
