PVC Leather Surface Treatment Solution

Introduction to Leather

Natural leather

Head layer leather: natural and delicate texture, excellent breathability and strong durability, with a full and soft touch feel
Second layer leather: low cost, high utilization rate of raw materials, clean and flawless surface after modification, good visual effect

Synthetic leather

PVC leather: extremely low production cost, excellent waterproof performance; But it feels stiff and has poor breathability
PU leather: soft and elastic texture, highly realistic appearance and touch, with mild breathability
Ultra fiber PU leather: excellent performance, soft and delicate feel, representing high-end synthetic leather
New bio based synthetic leather: environmentally friendly and sustainable concept

Leather Chemicals

Genuine leather: including chemicals used in the tanning, degreasing, and dyeing processes of genuine leather, impregnating adhesives, dyeing processes, and surface coating chemicals.

Synthetic leather: the core base resin of the synthetic leather skeleton, the adhesive that binds the synthetic leather to the substrate, and determines the core quality of various synthetic leatherLeather coatingFunctional additives, etc.

Product application areas

T0145 anti fouling treatment agent

T0145 anti fouling treatment agent is a type of anti fouling coating that achieves anti fouling performance by controlling the surface chemical composition and microstructure.

Lotus Leaf Effect to Anti fouling Treatment Agent

The mechanism of anti fouling action:

Reduce surface tension - material structure itself
Surface roughness modification - microphysical structure

The main ways of coating fouling are adhesion and inhalation

Adhesive pollution

Inhalation pollution

1. Design through molecular synthesis

Adjust the proportion of soft and hard monomers, reduce the surface stickiness, improve the appropriate coating rigidity, improve the coating density, reduce the coating surface energy by controlling the average particle size (400nm) of lotion, and introduce low surface energy groups containing silicon

2. Drying process control

Accurate temperature control and evaporation rate to form a dense coating

T0145 Anti fouling Treatment Agent - Application on PVC Leather Table Mat

Coating agent: T0145 and other domestic brands

Process: 120 mesh hexagonal scraper

Drying temperature: 135 ℃, 2 minutes

After coating, the glossiness (60 °) is 3.5GU

Test method:

1. The test liquids are: ① coffee liquid, ② tea liquid, ③ dark soy sauce, ④ red wine stain, ⑤ chili oil

2. Observe the anti fouling performance after 5 hours of dripping

T0145 anti fouling treatment agent has excellent anti fouling performance
