Q: What is the difference between exterior and interior wall putty？

1. Different material compositions: Exterior wall putty generally uses polymer materials with good weather resistance to adapt to changes in outdoor environments. Interior wall putty is generally made of environmentally friendly water-based materials to ensure indoor air quality. 2. Different construction methods: Exterior wall putty needs to consider factors such as waterproofing and moisture resistance, so strict processes and techniques need to be adopted during construction. Interior wall putty is relatively simple and has lower construction difficulty. 3. Different uses: Exterior wall putty is mainly used for repairing and decorating outdoor walls, requiring good weather resistance and waterproofing. Interior wall putty is mainly used for repairing and decorating indoor walls, requiring good flatness and decorative properties. 4. Different color choices: Exterior wall putty is generally white and can also be dyed as needed, while interior wall putty can choose different colors and textures according to personal preferences.

Exterior paints are coatings designed to protect and beautify the outside surfaces of buildings, structures, and other outdoor objects. Latex (Water – Based) Exterior Paints are the most widely used type of exterior paint today.

Product Features and Advantages

1. Thickening and Rheology Control

Good thickening property increase the viscosity of the paint, which is crucial for preventing sagging when the paint is applied to vertical surfaces such as exterior walls.

2. Water Retention

In outdoor environments, rapid drying due to sunlight, wind, or low humidity can lead to issues such as cracking, orange – peel texture, or poor adhesion. Good water retention slowing down drying process in exterior applications, and enhancing open – time of the paint, this provides more flexibility to painters.

3. Stabilization of Pigments and Fillers

Cellulose ethers help to keep pigments and fillers in a stable suspension within the paint, by which contribute to a more uniform color distribution in the painted surface.

4. Enhancing Film – Forming

A well – formed film provides better protection to the exterior surface from environmental factors like rain, snow, UV radiation, and wind.

5. Improving Adhesion

Whether the surface is concrete, wood, masonry, or other materials, better adhesion reduces the risk of the paint peeling or flaking off over time, which is a common problem for exterior paints due to weathering.

The Thickening Duo: HEC vs HPMC in Paint Applications

The choice between HEC and HPMC for paint formulations hinges on understanding their subtle differences.

Application of Hydroxyethyl Cellulose in Water-Based Paints

Paint additives are used in very small quantities, but can significantly improve the properties of paints, so has become an indispensable part of paints – Hydroxyethyl Cellulose in water-based paints. The thickener is a rheological additive. It not only can thicken the paint and prevent sagging in construction, but also can give the paint excellent mechanical properties and storage stability. For the water-based paint with low viscosity, Hydroxyethyl Cellulose is a very important class of additives.

Application of Hydroxyethyl Cellulose (HEC)

HEC is the abbreviation of hydroxyethyl cellulose. It is a white or light yellow, odorless, non-toxic fibrous or powdered solid, prepared by etherification of alkaline cellulose and ethylene oxide (or chloroethanol), and is non-ionic soluble cellulose ethers.
