t31 series

 

t31 series cycloamine epoxy resin curing agent was used as the main raw material and phenol, formaldehyde condensation reaction mannich further modified for the good of the new third generation epoxy curing agent. molecular structure containing phenolic hydroxyl (oh), burton amino (nh2) and amino sin (nh) of condensate, with high reactivity, curing speed, temperature and humidity environment curing. cured given good physical and mechanical properties.
for the preparation of adhesives, sealants, coatings, anti-corrosion, casting, and laminated materials. meet with epoxy used as adhesives and anti-corrosion chemical industry, civil construction, steel and glass coating industries.

surface treatment : body contact with the adhesive oil, dust, rust, etc., must be dealt with clean water;
even at room temperature (25 ° c), by adding 10% to 30% weight of epoxy curing agent tz series. curing may be a good effect;
even low temperature, it would be appropriate to increase the amount humid environment or underwater;
both increases may be needed to fill some filler, such as silica powder, silica powder, titanium dioxide, talc, mica powder;
even a thin layer of acetone, ethanol, mixed solvents (xylene : n = 1 : 1) as diluent.

application example :
      from january 2005 to march 2005, a company in jiangsu xinxiang motorcycle company to undertake a groove electrophoretic coating corrosion-resistant construction, equipment having good solvent resistance, the use of a long cycle characteristics, the use of a three wood and epoxy group holdings tz-500 selection for the main raw material for epoxy curing agent. because the temperature was lower (-5~5 ° c), often cold, rainy and snowy weather, a shorter period required, in order to ensure progress in the adjustment based on the formula used, the specific formula is as follows :

formula 1 or 2 by the formula can dry table 20 hours, and reached the curing properties of the facility.
this shows that using tz series epoxy curing agent has the following advantages :
>>> unlike raising curing agent used to shorten the period of use, speed up solid early time (table dry time), while significantly lowering the cost of production and construction.
>>> unlike reduce solvent use, and its role is appropriate viscosity control, but also not affect the use of solid shortening the beginning of time (table dry time), in addition to lower construction costs, but will also reduce solvent evaporation and the pollution of the environment and personal injury.
