Inquiry
  Post Date: Jan 02,2017
  Expiry Date: Jul 01,2017
  Detailed Description: Cas No. :25212-86-6 The furan resin for casting produced by our factory has a complete category,which has acid hardening self-hardening sand adhesive under normal temperature and thermal setting adhesive.This product is charactenzed bv low free fo rmalde—hyde content,small odor,high adhesive strength,good collapsibility,accurate sand mold(core)size and highly polishedcasting surface,etc.This product with excellent performance is applicable to various casting steel,casting iron and nonferrous metal coring and molding of muIling sand production lines for casting and manual mulling sand process.

1.Instruction
The added amount of resin is generally 0.9%-1.5%of the sand weight depending on the category of the sand;since the particle shape acid amount,mud content and water content,etc.of particles of the raw sand act relatively greater influence to the application effect of the resin,raw sand of appropriate model shall be adopted.
Both natural environment and relative tempe rature of the atmosphere will give a certain influence to the use of the resin,therefore,the amount of the curing agent shall be adopted approp riately according to the environment and the temperature of the sand.
The relative strength of the resin call be effectively improved by the silane coupling agent which is generally applied to the resin by the using unit prior to use The adding amount accounts for 0.2%-0.3%of the resin weight in general,and the service life in optimum shall be around one week.

2.Apphcatian Method of Thermo Set Resin
(1)Temperature 210oC±5oC
(2)Sand shooting pressure:0.5-0.7MPa
(3)Proportion:Sand:resin:curing agent=100:2.5:0.5
(4)Curing agent:a ammonium chloride:carbamide:water=1:3:3 b、urotropine 50%water solvent
(5)Sand Mixing Method:adding curing agent and mixing with sand for 1 min,then adding resin and mixing for 2min.

3.Furfuryl Alcohol Resin
This resin is a kind of perfect adhesive which has high adhesive strength and good thermal resistance,can resist corrosion from all organic solvents and can resist acid and alkali.It is widely used to cast stone anti-corrosion and wood binding,etc.

4.Storage and Transportation
The resin shall be kept in a coll and dry place:it shall be protected against insolation for a long time or getting close to thermal source:also pay attention to prevent acid substances getting into the product so as to avoid invalidation.Never directly mix the product with acid substances,othe rwise acute exothermic reaction will occur and accidents be caused.
