Silane-modified Adhesive Sealants

	Elastic Bonding Adhesive Sealant

Model Number

Flexibond MS-939

Flexibond MS-939 is a one-component elastic bonding adhesive based on silane-modified polymer. It combines the advantages of both polyurethane and silicone, and thus is a new generation elastic adhesive. It is free of silicone, isocyanate and solvent. It cures quickly to form durable elastomer when in contact with moisture at ambient temperature.

ADVANTAGES
l One component, non sag, easy to apply;
l Able to partially or completely replace conventional fasteners;
l High initial tack and fast positioning;
l Excellent adhesion without activator and primer;
l Good heat and UV resistance;
l Best environmental adhesive;

APPLICATION
Flexibond MS-939 is used for the bonding of parts in following industries: bus body, railway carriage, container, equipment engineering, air-conditioning and ventilation, metal and sheet metal working, plastics technology, ship building, etc..

ADHESION
Flexibond MS-939 has good adhesion on metal (fresh, parkerized, galvanized, painted), stainless steel, copper, aluminium (fresh, anodized, painted), glass, PC, PUR, ABS, polyester, most thermal plastics, EPDM, PS, PA, PVC, etc.. But prior test is absolutely necessary. For some substrates, the use of activator and/or primer will help to achieve optimal adhesion.

PROCESS
Cleaning:
Clean surface to ensure the surface being clean, dry, free of oil, grease, and of sound quality.
Activating/Priming:
Activators and/or primers may be required to achieve optimal adhesion depending on the nature of substrates.
Application of sealant:
Cut tip to desired shape and size. Puncture airtight seal. Install with hand or power operated gun and extrude the sealant into the joint. Clean excess sealant using hard rubber plate or finger wet with soap solution.
