Description
Bostik Simson MSR Prep Primer (M) – One-Step Surface Pre-Treatment for Improved Adhesion
Bostik Simson Prep M is a fast-acting, single-step surface pre-treatment designed to significantly improve adhesion on closed (non-porous) substrates when using selected Simson SMP (Silyl Modified Polymer) adhesives and sealants.
Developed for professional fabrication and assembly environments, Prep M prepares smooth or coated surfaces to ensure stronger, more reliable bonds, helping reduce the risk of adhesion failure on difficult materials.
With a rapid drying time (typically around 5 minutes, depending on substrate), it fits easily into production workflows while delivering consistent, high-quality results.
