4. PACKING
FB resin (solid) is packed in paper/plastic drum with plastic bag inside or paper/plastic compound bag and the options from 20kg~25kg packages can be selected by customers. The liquid FB resin is packed in metal drum of both 20kg or 200 kg.

5. APPLICATIONS
(1) Crush the FB resin properly (the smaller granular, the faster resolving speed), after that fill same quantity industrial alcohol to be immersed for approx. 24 hours to let it resolved, the resolution can be quicken if toss, stir and heating be made. On the container bottom, if small quantity of turbid substances can be seen, it will not affect the use and no need to separate since the larger molecular particles resolved slowly under normal temperature. Then add other material portions if necessary, and now the binding and gelatification can be done.
The solidification process when it is under adhering: 120 oC/2h + 150oC/3h + 180oC/2h.
(2) The following process relating to hydroxybenzene can be referenced in case to prepare compound materials: raise appropriately the hot molding temp, heating temp and prolong the processing time.
(3) In case prepare epoxy-solidifying agent, add the epoxy into the alcohol base FB resin and well mix, after that it can be applied. Its desired weight ratio is at 1:1(FB resin calculated as pure stuff without taking the resolution into account).
The solidifying process: 120 oC/2h + 150oC/2h + 180oC/3h.
(4) In case manufacturing the anti-friction-substance, directly grind FB resin then mix with other materials in same proportion and finally mold.

FB88#，FB89# -- SPECIAL HIGH-TEMP RESISTANCE RESIN FOR FRICTION MATERIALS

1. FEATURES:
This product is a kind of powder with the thinness between 80~200 mesh, which is especially fit for making high-temp resistant (HTR) resin mainly applied in friction materials of dry method and it can be also solved in industrial alcohol to make the friction materials of wet method and used as the binder to produce sand wheel of high performances. Mixed with FB88#，FB89#, the high-temp resistance and other performances of common thermal plastic hydroxybenzene (e.g. 2123#) can be improved.

2. MAJOR TECHNICAL DATA

The shelve life is more than one year.

3. USAGES AND APPLICABLE METHOD
FB88#，FB89# used as resin base can be directly mixed with rubber and other fiber fillers to become the material for molding. For the molding process, the relevant technology of normal hydroxybenzene and the molding temperature should be 10-20oC higher than the normal hydroxybenzene resin, moreover the longer warm-keeping time and thermal treatment’ time and temp should be maintained.
This series products used as brake blocks and discs’ base resin have been applied in the scale production and research has also done such as for brake blocks and discs for quasi-high speed and high-speed trains, high performance carbon fiber disc type car brake, poly (terephthaloyl -p-phenylenediamine) fiber enforced car brake drum, brakes for diversified engineering machineries, high performance clutch discs, resin base of C/C compound materials, binder for special sand-wheels etc. – an excellent high temp resistance basic material for brakes of super characters.

FB88#，FB89# can be used in the manufacture of anti-high temp refractory materials too.

MODEL F-51A, F-52B NEW TYPE HIGH TEMP RESISTANT EPOXY SOLIDIFICATION AGENT
This series is a solidifying agent of hydroxybenzene base of high temp resistance, the A type, of 200 mesh, can be directly applied in epoxy resins and B type, of 100 mesh, can be solved in industrial alcohol to be prepared into alcohol solution of 45% concentration. The test result at 15~20MPa (room temp) shearing strength can be gained on the steel strip sample bound with epoxy glue prepared with the said solidifying agent, even it can reach 6~10MPa when it is at 300 oC and it still assumes optimistic strength in case the steel strip sample under 400oC/1h sudden cooling then down to room temperature. It can make epoxy-coating materials of HTR too, with the features of HTR and acid/alkaline resistance.
Model F solidifying agents and Model Epoxy E-51 at iso-weight ratio show the solidification substance’s decomposition temperature at approx 380 oC and remains 38% residual carbon at 800 oC.
When the customers have the epoxy resin solidified with F alcohol solution, the solidification method of 180oC/3h should be adopted.

MULTIPLE FUNCTION EPOXY RESIN SOLIDIFYING AGENT – SP RESIN

1. FEATURE
SP resin is a new and multi-function epoxy base-solidifying agent with the virtues of solidification, rigidness, improvement and anti-inflammability. It is fit to use with acid anhydride family solidifying agent and its binding force is 1~2 times stronger than the single cid anhydride epoxy solidification, the anti-impact strength is 50% more than the former and the solid substances’ inflammability proof can be improved as well.

2. MAIN TECHNICAL DATA:

Add 0.5g HK-021 liquid acid anhydride (the actual test, increase the heating and decrease quantity down to 2.24%) into SP 0.2 and then test it.

3. APPLICATION
SP resin can be used in high-temp/low temp resistance binding, the filling of resin base compound materials, insulation materials and immersed oil motors and the sealing/filling of electronic components etc.

4. SP RESIN APPLICATIONS
1) SP resin is a brown viscose liquid suitable to be used with solidifying agent of acid anhydride and however it cannot be utilized with amine series materials. We recommend the recipes as follows: first mix well the 50% liquid acid anhydride, 20% SP resin, then add 100% #618 epoxy resin evenly tossed after that you can use it.
2) Solidifying Process
120 oC/2h + 150 oC/3h + 180 oC/1h, the binding shearing strength (#45 steel strip test sample to be under sand blast) can reach 330kg/cm 2. It can approach over 350kg/cm 2 if added with CTBN to improve the impact performance and inflammability dramatically. The mentioned recipes’ OI value is at 22.3 and can be solidified at 180 oC/3h.
3) SP resin, if at the low room temperature will assume gelatin-like and can be melt if heated appropriately.

5. SP resin is packed in paper drum with plastic drum inside and 10kg~15kg per package.
