BOSTIK 2000 PRIMARY SEALANT

TYPICAL APPLICATION WHEN USING WITH BOSTIK 5000 HMB SECONDARY SEAL

Bostik 2000 is suitable for use on all types of primary seal application equipment. Due to inherent minor differences between machinery, optimum performance is best attained by assessing the coating weight per linear metre on each side of the spacer bar rather than by specific temperature and pressure settings.The coating weight should be between 1.0 g and 2.5 g per linear metre on each side with the front and back coating weight as close to each other as possible (no greater than 0.5 g difference).

The spacer bar profile also determines the optimum coating weight achievable. A straight sided spacer bar will require a lower coating weight than a spacer bar specifically designed for dual seal systems (see diagram). This type of spacer can accommodate a higher coating weight.
