BoPin 630 Premium Paintable Acrylic Sealant

BoPin 630 is a single-component, water-based acrylic sealant produced using imported emulsion for superior performance consistency and finish quality. It cures by water evaporation at room temperature, forming a flexible, paintable seal that protects joint edges and blends seamlessly with surrounding decorated surfaces. The low-stress formula prevents damage to adjacent paint coatings, wallpaper and delicate substrate finishes during and after application. Suitable for interior dry-area joint finishing, wall crack repair and decorative trim sealing where a high-quality, professional result is required.

  • Surface Preparation — Ensure surfaces are clean, dry and free from dust, grease and loose material. Substrate moisture content must not exceed 12%.
  • Application — Cut cartridge tip at 45°, load into sealant gun and apply with steady, even pressure. Smooth with a wet spatula or damp finger within the working time.
  • Curing — Allow to cure at room temperature with adequate ventilation. Paint only after the surface is fully dry and no longer tacky.
  • Cleanup — Remove uncured product with water and a damp cloth. Cured product must be removed mechanically.
Limitations
  • Strictly not suitable for areas subject to prolonged water contact or immersion
  • Not suitable for structural joints
  • Not recommended when substrate temperature is below 5°C or above 40°C
  • Not recommended when ambient humidity exceeds 80% or substrate moisture content exceeds 12%
  • Not suitable for exterior joints with direct weather exposure
Tips
  • For best paintability, allow full cure before applying paint — painting too early may cause surface cracking
  • Slightly moisten very porous substrates such as plaster or brick before application to improve adhesion
  • Product must be protected from freezing during storage and transport
  • Store cartridges upright in a cool, dry location away from heat sources
