Bostik Simson Prep M 500ml – Adhesion Pre-Treatment for SMP Adhesives

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. Key Benefits One-step pre-treatment process for faster preparation Improves adhesion on smooth and non-porous substrates Fast drying (approximately 5 minutes, substrate dependent) Easy to apply Efficient, economical use Designed specifically for Simson SMP adhesive systems Suitable Substrates Bostik Simson Prep M can be used for pre-treating: Plain aluminium, steel, copper, and brass Powder-coated metals Lacquered metals (substrate testing recommended) Polyester (GRP) ABS PVC
