X_pand, functional filler for latex paint

Abb. 1: Elektronenmikroskopaufnahme von X_pandX_pand

The special grain morphology and extraordinary structure with blister-like air voids is obtained by means of a special procedure.

X_pand is a high brightness functional filler which gives enormous opacity to paints due to light  scattering at the microvoids.

X_pand in latex paint can be used to both improve the quality of paint and to reduce its TiO2 content.

 

X_pand effects positive changes regarding::

  • wet and dry opacity
  • whiteness
  • sheen reduction

without worsening appreciated paint characteristics, such as viscosity.

X_pand is a suitable replacement of classic matting agents like Diatomit in low-sheen paint formulations.

Replacing TiO2 together with CaCO3 by Alumo_Fill KK 15 considerably improves the quality of interior paints.

The productivity referring to a contrast ratio (CR) of 99.5% increases by approx. 7% on substituting 2% TiO2 (25% of the overall present TiO2) and 8% CaCO3 by Alumo_Fill KK 15.

In practical applications this improvement means that despite replacing 25% of the TiO2 present in the original formulation, only one coat of paint is necessary to get a sufficient opacity of paint compared to two coats of paint which are necessary with respect to the original formulation.

Results

The essential positive effects of replacing CaCO3 with Alumo_Fill KK 15 in tests with exterior paints have been:

  • increase of productivity
  • improvement of brightness
  • reduction of sheen

CaCO3 with Alumo_Fill KK 15 offers the opportunity to replace up to 4% of TiO2 in combination with 6% CaCO3 by Alumo_Fill KK 15 and thus to improve the quality of the paint.

R+D Products: Functional Filler For Dispersion Paint

Background

Development of a functional filler for dispersion paint.

Technical requirements

  • extreme high matting effect
  • brightness > 90, R 457
  • high wet opacity
  • high dry opacity
  • oil absorption < 70 ml/100 g

Material in test

R+D-Product 1: VP-FK-K
R+D-Product 2: VP-FK-FK
Reference: Diatomite, calcined
Bindersystem:
486,0g Water, demin.
500,0 Acronal 559
14,0 Additive

Procedure

100 parts of a binder system have been mixed with 30 parts of the filler. The mixture has been dispersed for 15 min. The paint was coated for measuring the optical characteistics. Wet opacity was measured directly after the application, dry opacity four days later.

Analysis

Wet Opacity:

Brightness over black divided by brightness over white. Measurement was done directly after application.

Dry Opacity:

Brightness over black divided by brightness over white. Measurement was done 4 days after application.

Gloss 85 °:

Measurement was done using a Micro Tri Gloss from Fa. Byk Gardner, accoding to DIN 67530, ISO 2813 and ASTM D 523.

Wet Opacity

Dry Opacity

Gloss, 85 °

Advantages

Wet Opacity:

Much higher wet opacity in comparison to Diatomit.

Dry Opacity:

Improved dry opacity of VP-FK-FK in comparison to Diatomit.

Gloss 85 °:

Equal gloss compared to Diatomit.

Oil absorption:

Lower oil absorption than Diatomit.

Improved mechanical durability of lacquer systems by adding functional additives

Introduction

The mechanical durability of lacquer systems like laminate or parquet coatings and an excellent transparency are some of the most important quality features of these products. Examples for the mechanical parameters are scratch resistence or stability against
abrasion. By using functional additives the mechanical durability should by improved while keeping the high transparency.

Summary

  • The additives can be worked in the lacquer systems very easily
  • Filling rate of the additives in the lacquer systems could be increased > 10 %
  • Desipte the high fgrad of filling transparency was at the same level
  • Changes in viscosity were acceptable
  • Scratch as well as abrasion resistence were improved dramatically
Improved UV-protection of wood coatings by using new inorganic additives

Introduction

UV-Protection is one of the most important criteria for wood protecting coatings. Additives to be used for UV-protection are ZnO, TiO2, CeO2 or products based on organic material. Tests are done, to find out the advantages of a new inorganic additiv for UV-protection.
