Product introduction
       This product is an adduct of VESTANAT IPDI, used as a crosslinking agent for hydroxyl-containing saturated polyesters in weather-resistant polyurethane powder coatings. Caprolactam ensures blocking of NCO groups below about 170ºC. This product is available in granular form.

 Features and Recommended Uses
       The use of VESTAGON B 1530 mixed with polyester with a large number of terminal hydroxyl groups can be used to prepare durable weathering decorative powder coatings with excellent process coating performance.
Examples of such resins are as follows:

 formula
     Equivalent application of crosslinking agent and polyester. In fact, when the requirements for coating performance are different, it can be used in the case of insufficient curing (NCO:OH=1:1), which is more economical.
Equivalent base mix formulations are as follows:

     In addition to pigmented powder coatings with more than 1% by weight of benzoin, clear powder coatings can be used as a protective layer for substrates and other paint systems.

curing
     The curing temperature of polyurethane powder coatings must generally be higher than the temperature at which blocking is eliminated (approximately 170ºC). During curing, part of the blocking agent is released from the coating as a gas. A prerequisite for good process coatability is that crosslinking should be carried out within the appropriate range (175-200ºC, 8-30 minutes).

 Process coating performance
       Both ε-caprolactam-blocked adducts can impart excellent mechanical properties to high gloss coatings. The multifunctional VESTAGON B 1530 is better than the bifunctional VESTAGON B 1065 in some special properties and in terms of weather stability and chemical resistance.

Application of Polyurethane Powder Coatings
       For many years, polyurethane coatings with VESTAGON have had a place in industrial exterior coatings and can also be used as interior coatings, depending on the industrial scope and field of application.
Some important examples of these applications are painting the following items:
•Agricultural Machinery •Excavation and Construction Machinery Components •Forklifts •Motorcycle Parts
•Bicycle Rack •Phone Case •Parts •Accessories

Package
       Polyethylene lined multi-layer paper bag, net overlap 25kg.

 store 
      It can be stored for a long time in an airtight container, and the package should be carefully sealed again after each removal of the material.
