What is the role of M E K OXIME?
Correct Answer
A. Anti skinning agent
Explanation
M E K OXIME is used as an anti-skinning agent. Anti-skinning agents are substances that are added to coatings, paints, and varnishes to prevent the formation of a skin or film on the surface when exposed to air. They work by reacting with oxygen and preventing oxidation, which is the main cause of skinning. M E K OXIME specifically acts as an oxygen scavenger, effectively inhibiting the skinning process and maintaining the quality and usability of the product.

What is the role of Silicon solution 1% in MTO ?
Correct Answer
A. Wetting and dispersing agent
Explanation
Silicon solution 1% is used as a wetting and dispersing agent in MTO (Methanol-to-Olefins) process. Wetting agents help to reduce the surface tension of a liquid, allowing it to spread more easily. Dispersing agents help to break down and disperse solid particles in a liquid, preventing them from settling. In the context of MTO, silicon solution 1% is likely used to improve the wetting and dispersing properties of the solution, ensuring better mixing and dispersion of reactants and catalysts, leading to more efficient and effective chemical reactions.

Identify the Coalescing agent combination ?
Correct Answer
D. Texonol & NX-795
Explanation
The correct combination of coalescing agents is Texonol & NX-795.
4.
Identify the surfactant combination ?
Correct Answer
C. IGSURF 6170 P & ALKAMULS 6170
5.
Which raw materials prevents micro organ growth in paint ?
Correct Answer
D. A & b
Explanation
The raw materials Rocima 623 and THOR IPS 30 are known to prevent the growth of microorganisms in paint. This means that when these materials are used in paint production, they help to inhibit the growth of bacteria, fungi, and other microorganisms that can degrade the quality of the paint over time.
6.
Identify the Resin combination
Correct Answer
B. R 3437 & R-2361
7.
Identify the RMs from R8 category
Correct Answer
A. DIETHYLENE GLYCOL & TEXANOL
Explanation
The correct answer is DIETHYLENE GLYCOL & TEXANOL because they are the only pair of substances listed that belong to the R8 category.
8.
Identify the powder raw materials combination
Correct Answer
B. RAMAFAST BLUE NAP 777 & TETRA POTASSIUM PYROpHOSpHATE
9.
Which raw material improves flow of the paint ?
Correct Answer
C. COIL FLOW ADDITIVE
Explanation
The COIL FLOW ADDITIVE is the correct answer because it is specifically designed to improve the flow of paint. This additive helps to reduce viscosity and increase the ease of application, allowing the paint to flow smoothly and evenly.
10.
Xylene importance in the resin Process ?
Correct Answer
D. All the Above
Explanation
Xylene is important in the resin process for several reasons. Firstly, it is used to maintain reflux, which is the continuous boiling and condensing of a liquid to ensure that the reaction proceeds smoothly. Secondly, xylene is used to remove water from the reaction mixture, as water can interfere with the resin formation. Lastly, xylene is also used to control the reaction temperature, as it has a high boiling point and can help regulate the heat produced during the reaction. Therefore, all of the given options are correct.
