(6), soluble / Diluted:
In general, the curing agent RFE with the following solvents have very good compatibility, but it must be tested for storage stability of the solution. RFE hardener can be esters and aromatic hydrocarbon (for example: acetic acid has been acetate, butyl acetate, 1 - methoxy -2 propyl acetate, toluene and xylene) dilution, aliphatic hydroxyl classes are not suitable for solvents. Products, as most of the curing agent, curing agent RFE can not be diluted to non-volatile matter content of less than 35%, a low level of long-term storage solution adhesives may cause turbidity and sedimentation phenomena, you must use the PU-class solvents (water content of less than 0.05%), solvents not containing active components, such as hydroxyl or amino.
(7) Compatibility:
Hardener RFE can be with the following curing agents and curing agent mixed model grades. However, it must test the compatibility of the mixture, curing agent and curing agent RFE can be N3200, N3390, Z4470, HL, IL and L mixed with most exemplary grade polyester curing agents, such as a model 650,651,670, 680,690 and RD181 mixture can also be an exemplary curing agent, and acrylic acid ester A160, A265, A365, A450, A565, A665, A760, A870, as well as polyether curing agent mixed model 550U.
(8) Application:
RFE hardener and curing agent can be a model 650 or 651 to the preparation of mixed-weather outdoor use without fading paint, which has good wear resistance, solvent resistance and chemical resistance.
The curing agent RFE can be mixed with the curing agent can be used as a model 670 with a low temperature toughness of the coating, but these systems must be forced dried.
The curing agent and curing agent RFE model A265, A365, or 680 two-component mixture can be prepared Automotive Refinish will be N75 curing agent and curing agent can be a model A160 or A165 to the preparation of industrial paint mixed with the curing agent mixed with the preparation of wood model A450 paint.
Curing agent RFE will be added to cellulose nitrate, alkyd resin or vinyl chloride copolymer coatings for the substrate can greatly improve its film properties, such as scratch resistance and solvent resistance, but must be carefully tested.
(9) Storage:
Hardener RFE right moisture sensitive and must therefore be stored in original sealed containers. If the curing agent will be stored in suitable conditions, N75 (normal room temperature), its stability can be maintained for at least 6 months. The percentage of free HDI monomer content can be stable for at least two years.
(10 Security:
Due to different hydrogen-containing solvents and poly-acids, so dealing with this product, be extremely careful.
Should refer to the safety data sheet, this data table contains a label, transportation, storage, processing, product safety and ecology, etc., while the loose-leaf DD should also note that our general information section within the section 1,3, in which technical data with additional data. In addition, countries should also note that the existing controls on the disposal poly-isocyanate esters and solvent regulations. This product is flammable substances, therefore, the container must be away from the fire source. Must be taken to prevent electrostatic adsorption of measures to deal with the product to be carried out in the explosion-proof plant.
Avoid skin and eye contact with the product or the inhalation of the vapor body, it is recommended to wear safety goggles and protective gloves.
When spraying, must be protected from the spray respiratory damage, it is necessary to wear a respirator.
This product diisocyanate monomer content of less than 0.5%, if the products properly stored, in six months time will not exceed this value, inhalation hazard when the stimulation caused by a new low, in some cases, allergies can occur to reflect.
This product is not into the sewerage system.
