Product Description

Sayerlack Water Based Cross Linker for Glass - XA4095

Sayerlack Waterbased cross linker can be add to basecoat, lacquers or topcoats to increase hardness, chemical resistance and blocking resistance. It also improves the adhesion to glass surfaces.

XA4095 is a cross-linker for waterborne coatings. When added at 2-3% to relevant waterborne products before use, it promotes adhesion on glass.

Given the variety of surfaces available on the market, a preliminary adhesion test is always required and recommended. When added at a concentration of 1-2% it considerably improves hardness, abrasion resistance, resistance to aggressive chemicals and blocking resistance. It should be used in all situations in which these characteristics are particularly desirable (e.g. topcoats for furniture requiring hardness and high chemical resistance, topcoats for door and window frames to be located in countries with particularly hot climates, etc.).

  • Excellent thermal shock resistance
  • Promotes exceptional adhesion properties

Technical Detail

Because of the high viscosity, XA4095 is to be added in the percentages shown on the data sheet and under stirring conditions (preferably mechanical). If not stirred when being added to the coating, it may generate clots which would force product filtration to make it applicable. The introduction of crosslinking agent in a product, normally does not involve viscosity changes; however, a dosage exceeding 2% does increase viscosity and might cause gelling.

Additional Technical
This product is for professional use only. XA4095 loses its effectiveness within 48 hours after being added to the coating. After this time it is necessary to add fresh cross-linker, mixing the product left over with an equal quantity of fresh material. The addition of XA4095 to basecoats or self-sealers must be evaluated carefully, as it may cause cissing or poor adhesion problems of the topcoat.
