phenolic resin for shell and core, resin coated sand, solidity type

China manufacture favorable price solidity phenolic resin The ZP series is the resin that used for coated sand, and it is in fast  curing speed and high quality. It is a solidty resin that in amber color, looks like corn. It can be mix with sand then make sand mold to product more precise castng. And we can offer samples on free for customers who are interested in our product.   Each product test in strict standard, and must be in good quality:   Our company has our own phenolic resin workshop that can produce 5000 tons phenolic resin every years.     Our company also equip an professional testing center that to test each product we offer confirm to quality standard .        All of our resin coated sand have pass ISO9001:2008 certification:                          The advantage of using phenolic resin for coated sand: 1.  It has good mobility that easy to coat; 2.  It has low free phenol that can improve workers’ working condition and environment pollution; 3.  It has high strength that can reduce the usage of resin which can reduce cost and improving resin coated sand quality; 4.  It can increase diffusivity by using special formula to reach high-temperature behavior and high temperature strength.   common type and main technical index:

Index Model	Softening point (°C)	Free phenol (%)	Gather speed (150°C/s)	Fluidity (mm)	Recommended application
ZP204	85-95	≤3.5	45-60	60-90	General purpose/ shell or core
ZP205	85-95	≤3.5	30-40	40-70	Fast gather speed/ shell or core
ZP206	95-105	≤3.5	35-45	≥35	High temperature/ shell or core

    Considerations:
    1,Use place should maintain good ventilation.
    2,Must be maintained in a cool dry place, heat-proof, anti-exposure, it is best to cold storage.
    3,ZP204, ZP205, ZP206 guarantee period of up to 3 months.
    4,Those who allergy to phenol and formaldehyde should be protection.   Package:                                                     25kg in pack
