CROSSLINKING AGENT TP1530 (for polyurethance powder coating)
Description:
HARDENER TP1530 is equivalent to Degussa B1530 ,is a polyisocyanate adduct used in combination with hydroxy functional resins , Due to the Caprolactam blocked NCO-groups it is stable during processing up to the unblocking temperature of more than 180°C/338°F (15 minutes) .
Higher crosslink density and outstanding chemical resistance; NCO% 15.6; functionality 2.5; mimimum baking temp Tg-value 50°
Typical properties:
Advantages:
Numerous OH-terminated polyerter and acrylics can be used to achieve weather-resistant decorative powder coatings with excellent physical properties. These polyols have a determining influence on the prformance of the coatings .
Curing conditions:
The curing temperature for PUR powder coatings based on 1530 lies above the splitting temperature of about 170ºC .A prerequisite for good physical properties of a coating is sufficient curing in the range of 180ºC 20 minutes up to 200ºC 10 minutes total oven time ,according to the following standard procedures.
Premixing : MTI -MIXER 2'-500rpm
Extrusion: W&P ZSK 30 90ºC-250RPM
Application: manual spray gun 80kv ,steel panels 0.88mm
Curing : Air -circulated heraeus oven ,coating thickness 55-75 um
Usage:
Applications for polyurethane powder coatings:
PUR powder coatings have been successfully used for many years in both exteriorand interrior applications such as :
√ Motor vehicle parts
√ Fittings
√ Bicycle frames
√ Fork lift trucks
√ Exterior furniture and lawn equipment
√ Agricultural machinery
√ Appliances
√ Telephone booths
Storage & Packing:
The products is delivered in flat bags , net weight 25kg , If kept (0-40ºC) and dry in closed bags the product can be stored for at least 1 year in accordance to the specification .all opened bags should be carefully resealed immediately after use.
