Resin (Qual Rez by MARPOL PVT. LTD)

Qual Rez by MARPOL PVT. LTD.

Resins are the fundamental building blocks of a Powder Paint/Coat System. Marpol Pvt. Ltd. is the only company in the paint industry which Manufacture's its own Polyester Resin (Qual Rez) from its inception in 1986.

Resins can be broadly categorized into two types:

  1. Thermosetting Resins: (Epoxy, Epoxy Polyester, Urethane Polyester, Polyester TGIC etc.)
  2. Thermoplastic Resins: (PVC, Polyolefins, Nylon, Polyester, Polyvinyl Flouride etc.). Marpol makes Thermosetting, Pure Polyester Resins (Qual Rez) for Powder paints.


​Pure Polyester Resins can be further categorized into two types:

  1. Polyester Resins for HYBRID POWDER SYSTEMS.
  2. Polyester Resins for PURE POLYESTER POWDER SYSTEMS.

Hybrid Powder Systems are recommended for INDOOR use whereas Pure Polyester systems are recommended for OUTDOOR use.

 

HYBRID POWDER SYSTEMS are also known as Epoxy Polyester (EP) Powder systems as they use Epoxy resin for curing.
Polyester Resins for Hybrid Powders can be broadly categorized into 3 types of chemistries:

  1. 70:30 (70% Polyester: 30% Epoxy) Marpol Code 40-004050
  2. 60:40 (60%Polyester: 40%Epoxy) Marpol Code 40-004039
  3. 50:50 (50% Polyester: 50% Epoxy) Marpol Code 40-004034

Marpol also makes a Master Batch Catalyst 40-0041(c) and a hybrid resin coded 40-004035 for achieving special properties in various powder finishes.

PURE POLYESTER POWDER SYSTEMS are also known as Pure Polyester (PP) TGIC OR Pure Polyester (PP) Primid systems as they use TGIC and Primid as a cross linkers during curing.
Pure Polyester Resins for PP Powders can be categorized into 3 types:

  1. 93:7 (93% Polyester: 7% TGIC/Premid) Marpol Code 40-004066
  2. 96.5:4.5 (96.5 polyester : 4.5% TGIC premid)  Marpol Code 40-004068
  3. 93:7 Highly Durable Polyester (HiDura) (93% Polyester : 7 % TGIC) Marpol Code 40-004080

Following are some of the Attributes of Hybrid (EP) and Pure Polyester (PP) resins:

HYBRID POWDER SYSTEMS (For Indoor Use)
 
Code
 
Description
 
EP 40-004050 Used for high gloss powder systems with smooth finishes. Helps formulators create a cost effective glossy powder formulation with balanced mechanical and chemical properties.
 
EP 40-004039 Used in glossy structure finishes. Combined with 40-0041(c) gives excellent structure finishes with high impact resistance.
 
EP 40-004034 Used in powder systems which need excellent flow properties and clarity in coatings. Gives formulators the best balance in Mechanical, chemical and flow properties.
 
EP 40-0041(c) Is a Master Batch Catalyst. Helps formulators achieve high impact resistance and best cross linking properties. Helps in tuning the rheological properties of the coating to achieve desired structure patterns.
 
EP 40-004035 Used in formulations for hybrid matt and satin finishes. Offers excellent smoothness to the finish.
 

 

PURE POLYESTER POWDER SYSTEMS (For Outdoor Use)
 
Code
 
Description
 
PP 40-004066 This is a linear resin used in formulations requiring excellent smoothness and gloss.
 
PP 40-004068 This is a branched resin with well balanced mechanical and chemical properties. Suitable for all formulations. Ideal for PP structures.
 
PP 40-004080 This is a highly sophisticated resin with very high weathering durability. It provides 3 to 5 times better weathering resistance compared to standard polyester resins. Able to fulfil AMAA and QUALICOAT standard requirements.
