Admark has well qualified research team engaged in developing newer technologies and processes to meet Industry demands such as low temperature curing, low VOC, corrosion protection and high performance in adverse environmental conditions.
Admark Polycoats also manufactures standard epoxy hardeners like polyamides, its Epoxy Adducts which have remained work horse of epoxy coating and adhesive industry for several decades. However, high viscosities and slow drying at low temperatures have been major draw backs of polyamide hardeners. Hence they are suitably used in tropical climate. However, coating formulators have to use considerable amount of solvents to make the coating compositions application friendly.
The increasing demand by environmental protection agencies, low VOC levels is increasing pressure on coating formulators to develop high solids or solvent free coatings those are application friendly, less polluting and durable. There is a need also for development of coatings that can cure at very low temperature, some times sub zero temperatures.
Though several mechanisms have been worked out, Phenol-Formaldehyde-Amine condensates or Mannich bases gained considerable importance due to its fast curing mechanism at low temperatures. These hardeners are less susceptible to carbonation. Different Phenolic compounds have been used. However, due to REACH regulation there may be restriction on the use of some of the Phenolic Compounds. Cardenol, naturally available phenolic compound is therefore getting wide recognition for making Mannich bases which are commonly known as Phenalkamines
Admark's R&D is in constant surveillance of newer technologies to meet the industrial requirements. The R&D team has developed phenalkamines, its Epoxy Adducts, which are fast curing at low temperatures. The lower viscosities of these hardeners help the coating formulators to meet VOC requirements. These hardeners also offer versatile properties like excellent flexibility, salt water and chemical resistance, moisture insensitiveness, fast cure at low temperatures and longer pot life. These hardeners therefore find wide application in Marine, Protective coatings, offshore, industrial, concrete coatings.
Admark Polycoats has also some diluents based on Cardenol in the range of the products. These diluents are used for reducing viscosity of Epoxy resins and cost reduction.
