Different types of coatings crosslinking agent,Tie-in after epoxy resin can be used for wood, fiberglass, and most of the metal bonding.
Different types of coatings cross-linking agent USES:
Quick crosslinking type: general adhesive, applications and anticorrosive coating fabric.
Slow crosslinking type: general adhesive, applications and anticorrosive coating fabric. For longer work time or temperature relatively warm environment.
Super slow crosslinking type: general adhesive, applications and anticorrosive coating fabric. Used in high temperature environment.
Transparent crosslinking agent: applied to varnish finish, natural wood finishes, clear and colorless coating fabric application.
Slow crosslinking agent is suitable for the under high temperature, the need of long working hours and crosslinking general coating and adhesive application. Can form solid coating of high strength, moisture-proof, it has excellent bonding properties and anticorrosive coating properties. Cannot be used for colorless coating.
Transparent crosslinking agent is designed for coating and application development of glass fiber cloth, used to use texture clear, moistureproof, clear carbon fiber or natural lumber.
In humid conditions, crosslinking agent not deep or dark. Don't need too much in the applications of thin film, coating surface polishing. Professional or like using transparent crosslinking agent construction personnel for the first time, because it is reliable and easy to use. More than three layers and it can be finished in one day, no additional surface treatment.
When fill the glass fabric need less coating, in most cases, the final coating need to grinding in the next day. Used for boat speed faster. Construction workers also like fine glass fiber invasive, it such as slow crosslinking, low viscosity of epoxy resin will not flow down along the vertical plane.
Transparent crosslinking agent intensity is very high, can be used as structure adhesive in gluing and laminating. It and has good compatibility with the paint and varnish. When as a UV filter surface coating, transparent crosslinking agent in the UV inhibitors can provide the perfect effect.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine
English name: Benzenediamine, ar, ar-diethyl-ar-methyl-English aliases:Diethyltoluenediamine; ar, ar-Diethyl-ar-methylbenzenediamine;Diethylmethylbenzenediamine;
CAS No. :68479-98-1
EINECS No. :270 -877-4
Molecular formula: C11H18N2
Molecular Weight: 178.28
Boiling point: 310 ℃
Refractive index: 1.581
Flash Point: > 140 ℃
Inchi: InChI = 1/C11H18N2/c1-4-8-6-7 (3) 10 (12) 11 (13) 9 (8) 5-2/h6H ,4-5,12-13H2 ,1-3H3 density : 1.022
Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Super slow crosslinking agent suitable for in high temperature or damp environment, or need to work longer hours at room temperature conditions common coating and adhesive application. The working time is about twice the slow crosslinking agent. Can form solid coating of high strength, moisture-proof, it has excellent bonding properties and anticorrosive coating properties. Cannot be used for colorless coating.
Stored at room temperature, it is necessary to keep the lid of the barrel body shut down to prevent pollution. Through the correct storage, resin and crosslinking agent can be used in many years. Has not used up after long time storage products, need to check the measurement accuracy of the pump, and extract some samples to verify whether can normal crosslinking.
With the passage of time, the viscosity of the resin increases, repeat solidification during storage or release will cause resin crystallization. The resin is heated to 52 ℃, then stir to dissolve the crystals. With the passage of time, the crosslinking agent may be dimmed, but its performance is not affected by the color, can be normal use.
If in the same surface coating agent and using new member at the same time, please pay special attention to the change of the colors.
Epoxy resin with epoxy groups and hydroxyl zhong, para hydroxy can react with isocyanate. Epoxy resin as polyols containing hydroxyl component directly join polyurethane adhesives, use this method only hydroxyl groups take part in the reaction, epoxy group failed to respond.
With acid resin, carboxyl, epoxy ring opening, then react with the isocyanate polyurethane adhesives. Epoxy resin can be dissolved in ethyl acetate, adding phosphate heating reaction, the adduct of added to the polyurethane adhesives; Early sticky glue; Heat resistant and hydrolytic stability can improve reaction can also be used alcohol amine or amine to produce the polyol, uncle of nitrogen atoms in the adduct exist, can accelerate the NCO reaction.
