OUR YANKEE CHEMISTRY RANGE

PETROFER offers a great portfolio of products to optimise Yankee drying, life and paper quality. BASE COATINGS of our COTAC H series support technical requirements. They provide consistent process conditions and optimised paper quality while protecting the Yankee cylinder. MODIFIERS of our COTAC C/P series can optionally be used together with base coatings. Phosphate based products protect the Yankee dryer surface from corrosion and wear while increasing the life of the doctor blade. Polymer based products improve the paper quality. EDGE TREATMENT of our COTAC P series prevents wear and trim adhesion as well as corrosion. RELEASE AGENTS control the adhesion between the paper sheet and the drying cylinder while providing lubrication of the doctor blade. PETROFERs products are compliant with local regulations such as BfR XXXVI

OUR EXPERTISE

PETROFER has more than 40 years of experience with products for Yankee coating applications and have worldwide references of loyal customers. A perfect chemical product combination as well as its dosing quantity will be determined by our field technicians in surveys. This enables an optimal adjustment to the previously agreed test targets. As the technical leader of coating applications, we continuously establish new innovations and expand our diverse portfolio, while offering excellent service in close collaboration with our customer. Additionally, our well-equipped laboratory is able to make data predictions about the adhesion performance of our product combinations at the Yankee cylinder. This way we prevent production losses during trials, and are able to support with definitive ideas of the required changes to optimize production and quality.

OUR PRODUCT RANGE IN DETAIL

BASE COATINGS

Our base coatings of the COTAC H series provide individual control of adhesion and cylinder protection. They support the requirements of technically advanced production leading to process stability. Our products optimise paper quality while protecting a wide array of Yankee cylinder surface materials, and doctor blades. PETROFER base coatings are based on various types of polymers, additives, plasticisers and phosphates. Our products are suitable for different machine designs, furnishes and speeds.

MODIFIERS

PETROFER modifiers of the COTAC C/P series are based on various types of polymers, softening agents and phosphates. Most of the quality characteristics of the paper produced can be achieved on the Yankee cylinder. Modifiers combined with base coatings mean quality parameters are individually adjustable. This way softness, volume, crepe and stretch become optimised. Phosphates protect the cylinder from corrosion and wear in combination with base coatings, while improving the life of the doctor blade.

RELEASE AGENTS

With our RELEASE AGENT series, the adhesion of different paper grades and machine settings is controllable. Our products are available with different release effects for optimal control of the creping process. To cover your individual needs, PETROFERs RELEASE AGENT products are differentiated into products that contain mineral oils, native oils, are semi-synthetic, fully synthetic or water based.

EDGE TREATMENT

Edge deposits can significantly impact the paper production. PETROFERs edge treatment products of the COTAC P range prevent wear and corrosion while dissolving undesirable deposits. Removing edge build-up improves blade life and reduces blade vibration. The results are increased machine efficiency with reduced sheet breaks and machine maintenance. Our products are water based using high performance formulations.

APPLICATION EXAMPLES

A leading international tissue producer was suffering from chatter marks on the Yankee resulting in lower machine speed, poor tissue quality and reduced blade life. PETROFER PAPER CHEMICALS team precisely analysed the conditions and recommended a soft base coating together with a strong release product, a suitable edge treatment and blade settings. With our advanced coating chemistry, the vibration could considerably be reduced, machine speed was increased and a better paper quality was achieved. Further damage to the Yankee was stopped and the time until the next grind was extended. As a consequence the customer saved money and improved productivity.
