DOWSIL™ AP, the essential acetic silicone sealant


DOWSIL™ AP : high elasticity and flexibility


DOWSIL™ AP is a multipurpose acetic silicone sealant. It is used for bonding and sealing applications.
DOWSIL™ AP combines elasticity and flexibility with excellent adhesion to a variety of non-porous substrates such as glass, glazed ceramic tiles and aluminium…


Benefits of DOWSIL™ AP


  • Multipurpose
  • Easy to apply
  • Does not sag
  • Good adhesion to many substrates
  • Cures at room temperature


Some examples of applications where the effectiveness of the DOWSIL™ AP has been proven:


Before applying DOWSIL™ AP, the substrate must be prepared. All surfaces must be clean and dry. Degrease and remove all pollutants that could affect the adhesion. For this purpose we suggest the use of surface preparation products from the Socomore range
