Molding resin XP 1-1701

casting

No-bake Resin for Aluminum Casting binder system consists of three parts: Part I Polyalcohol, Part II Polymeric Isocyanate and Part III XC Curing Agent. Excellent fluidity of the mixture, easy for manual or mechanical sand filling, good roughness on the casting surface and high dimensional accuracy. Rapid curing speed and curing homogeneously with excellent thorough-hardening. Good collapsibility of sand core (mold) after pouring, easy for sand removal. How to use The addition rate of the resin should be 1.2-2.0% (by sand weight) according to the quality of original sand (reclaimed sand) and technical requirements. Resin Part I: Resin Part II = (40-60%): (60-40%), 55%:45% is preferred. When do the mixture, use curing agent to adjust the stripping time. When the temperature of sand is 30℃, the stripping time is 6-10 minutes without curing agent. If use intermittent sand mixer, firstly add catalyst into Part I resin and blend with sand for 1-2 minutes, then add Part II resin into the mixture to blend for another 1-2 minutes evenly. If use continuous sand mixer, firstly blend catalyst with Part I resin, then pump Part I and Part II into the sand mixer. Core making or molding instantly after mixing, in case of fluidity fall for mixture sticky. If need get single or small quantity of hand made product, we propose mixture concocted as below: Firstly concoct catalyst with Part I resin evenly, and then blend with original sand (reclaimed sand) for 1.5-2 minutes evenly. Add Part II resin into original sand (reclaimed sand) then blend for 1-2 minutes evenly. Blend the two kinds of mixture together evenly when using.
